A fabric inspection apparatus comprises a fabric supply roll 1, an illuminated opaque viewing screen 4 over which the fabric 2 passes from the roll 1, a wind-up roll 7 and a presser roll 11 to drive the roll 7 by frictional contact therewith, the roll 11 being mounted on a member 14 pivotable about a fixed horizontal axis 13 so as to allow movement of the roll 11 away from the axis of the roll 7 as the bulk of the fabric thereon increases. The rolls 1, 7 are mounted on supports (not shown) of known construction. The fabric 2 passes from the roll 1 around driven take-off rolls 3, over the inspection screen 4 illuminated from the rear by a light source (not shown) and over a roll 5 which ensures that the fabric 2 is maintained flat as it passes over the screen 4. The fabric then passes to the freely-rotatable roll 7 by way of guide means 6 including selvedge-uncurling devices 8, guide rolls 9 and a scroll roll 10 arranged to rotate so as to tend to oppose the advance of the fabric 2. The roll 11 is driven through a belt-and-pulley system 12 from the shaft 13. The member 14 comprises an L-shaped arm pivotable about the axis of the shaft 13 and is formed with a quadrant-shaped curved portion the centre of curvature of which coincides with the axis of the shaft 13. Attached to one extreme of this curved portion is an inextensible flexible suspension 15 for a stack of weights 16 so that the total force exerted on the surface of the fabric during wind-up is constant for given weights 16. The curved portion may have a groove formed therein or may be provided with teeth and the suspension 15 is a pulley cable or a chain, respectively.

Patent GB-446752-A (GB)
Abstract: 446,752. Colour photography. KODAK, Ltd., Kingsway, London.-(Assignees of Tuttle, F. E. ; 343, State Street, Rochester, New York, U.S.A.) Nov. 5, 1934, No. 31693. Convention date, Nov. 18, 1933. [Class 98 (ii)] The component images on a lenticular film are printed onto a lenticular blank film by illuminating the images by a point or linear light source, altering the apparent position of the light source with respect to the film by deflecting means arranged between the light source and the film and separately and successively projecting the images with the axis of the projected pencil for each component passing approximately through the centre of the component, the centre of the curved surface of the corresponding lenticular element, and the optical centre of the objective, the light being directed by deflecting means onto the copy film so that the axis passes through the centre of the curved surface of the lenticular element and through the centre of the image area, the images being thus printed on the copy film in positions corresponding to their positions on the original film. The deflecting means may comprise refracting prisms. The apparatus may comprise an objective, the effective diameter of which may be such as to subtend at the copy film an angle not greater than that subtended by a single band of the filter used in projection, feed means for the films, and a carrier in front of each gate for bringing the prisms before the gate in succession. Fig. 2 shows the printing of a lateral component, the original film 12 being illuminated by a linear light source 10 and condenser 11, the width of the image of the light source incident on the original film being less than the width of the central band of the image. Prisms 23, 24 are arranged before the gates of the original and copy films 12, 16 and a plane parallel glass plate 25 is interposed in the light path to compensate for the displacement of the image due to the prism 24. A similar arrangement with the prisms reversed is used for printing the second lateral component. When printing the central component, glass plates are inserted for shortening the light path to correspond to that of the lateral components. Fig. 6 shows an apparatus for moving the prisms and glass plates in front of the gates. The prisms 23, 26, for printing the lateral components and the glass plate 21 used when printing the central component are mounted in an arm 39 pivoted at 40 and moved by a cam 44 having three arcs concentric with the axis of rotation of the shutter which carries the cam follower 43 so that no movement of the arm 39 occurs when the apertures in the shutter are passing in front of the prisms or block. The apparatus is duplicated at the gates or that at the printing gate may be replaced by decentred lenses. The apertures in the shutter may be of different extent to vary the times of exposure of the components. The process may be used for printing lenticular films bearing two component images, e.g. stereoscopic images or the component images of a two-colour process.

[Also in Division H2] In a temperature detection system, actuation of the indicator device by wiring faults is prevented by a shunt switch across the indicator which is opened by the temperature sensing element when the temperature to be sensed is reached. The thermal switch (see Division H2) is actuated by the gas pressure developed when a gas evolving material 10 is heated. When the operating temperature is reached, normally open contacts 16, 17 are closed connecting the supply 23 to the indicator 25, and normally closed contacts 18, 19 open to allow the indicator to operate. In a modification, Fig. 4 (not shown), the normally open contacts are omitted, and the indicator is permanently connected to the supply through a load resistance. The material 10 may be heated for test purposes by a test circuit comprising battery 30 and switch 31. A number of detection elements may be connected to a common indicator, Fig. 3 (not shown), with their normally open contacts connected in parallel, and their normally closed contacts connected in series.
